Description
pH-Fix 5,1–7,2 is a ready-to-use indicator stick range for rapid semi-quantitative pH determination between 5,1 and 7,2. The fixed colour scale covers the steps pH 5,1–5,4–5,7–6,0–6,3–6,6–6,9–7,2, enabling clear visual readout in the weakly acidic to neutral region without additional reagents or instrumentation. Each stick measures 5,5 × 85 mm and is designed for direct immersion and comparison against the printed reference colours. Supplied in packs of 100 test sticks, the format suits routine checks in laboratories, process control, education and quality assurance where a compact, portable pH tool is required. These indicator sticks from manufacturer Macherey-Nagel belong to the established pH-Fix series and are intended for aqueous samples within the stated measuring interval. The stick form simplifies handling and disposal compared with loose indicator papers, while the graduated scale supports reproducible visual assessment across repeated tests.

Questions about pH-Fix 5.1-7.2
What is this article?
pH-Fix 5.1-7.2 is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Test strips & indicator papers, inside Test kits & water analysis, in Lab chemicals.
A test strip or indicator paper changes colour when it meets an ion, a pH or another analyte. It is a fast, coarse reading. The scale printed on the pack is the only scale that strip may be read against. A wet finger contaminates a pH paper before the sample does.
A test kit turns a chemical question into a colour, a titre or a reading on a strip, so the operator does not have to assemble the method from separate reagents. A cuvette test is a ready optical cell. A strip is a field reading. The range printed on the kit is the range where the answer means something. Outside it, the kit is silent or wrong. The substances inside are on PubChem. Water measurement traces to NIST.
Which category should I open next?
